To all whom 'it'may concern:

Be it known that I, GEORGE B. DA5tox,'of

Glenside, in the county of Montgomery and in the State of Pennsylvania, have inventedl Va certain new and useful Improvement m Gas-Burners for HeatinP Pur oses, and do herebydeclare that the ollowing is a full,

" clear,` and exact description thereof.

' My invention relates, to an improvement in burners, and especially burners which are used for burning gas for heating purposes, such as in power plants.

Although my Vburner 1s applicable to the of any character, it has been especially igned for use in connection with the burning of producer gas It has veen extremely dncult in the past to secure 'an ellicient` producer gas burner,r owing to the Afaetthat such asmallproportion of air is required` for combustion that -it` is exceedingly diicult to secure an intimate mixture o the air with the gas. f The burners which have been used for thisA purpose previously, admitted 'an excessive amount of air to compensate for'the lack of homo eneity obtained in the mixture, This resited in a marked lowering of the temperature of the Haine, as the excess of air was of necessit heated during the procse c.. burin" the ...m

i burner has been designed to avoid this culty, and in its operation a erfept mixture of a minimum quantity o air'with a I ranging the parts in such a way that almost any element thereof can be adjusted so as t locate it in the most efficient position tu o tain the best results. i

I have shown one embodiment of my invention in the accompanying drawings, in

which,

F ig. 2Jpartly in elevation. .n the drawings, l is a burner barrel, or outer easing, havin with aplurality of air inlets 7 whic permit air to enter into the body of the barrel or casing 1,' screw-threaded so that number of them maybe pluggedif necessary. The

steam pipes terminate within the head I The fuel gas pipe 5, on the contrary, paszes into the interior of the easing to approxmitely the center thereof, where a hollow head, 8 is lattached to it. The head 8' is 9 land .is provided at its rear with a plurality of peripnerally located apertures or )et openings 10. The diameter of the hollow head 8 mentof the lburner taken on line 4-4 of y, i

located at itsrear a A' Ilan re 2 which is a e'ted to be bolted to a,y

closed at the front by an iinperforate plate y l is'somewhat` smaller than the diameter'of the bore of. the casing 1, so as to leave room l r for the assa of the mixed as and air around t e ho low head to the` y ront of the burner casing, and the hollow head 8 is caused to be supported in ay concentric osipassin through one side thereof.

In t ve front of the burner I provide d mix- .ing' or je; member having a tapering go ning 1 4, whichV is designed to be adJust le within the barrel of theA burner 1, and inY which it may be secured in'any desired po- In theoperctionof the dev-ice,v the col'ie 100 12, the'pipe 5 and its attached hollow head 8 and. the member 14 are adjusted in their l 0 ongitudinull 1n the barrel 1. -LThe ipe 5 has situ- Vate upon it a -cone 12', ren ered adjustable thereon by means of a tightening screw v13' Y sition in any suitable'manner by means of most ecient positions. Fuel gas, preferably producer. gas, xsthen .led into the burner through pipe 5, .whence it passes into the bod',y of the hollow head 8 and, es-

"capes through the peripheral jet openings' 10 intothe'- restricted portion' of the burner, acting as a.- mixing chamber, situated between the adjacent' faces of the hollow head 8 and the cone 12. l Simultaneously with the 5 entry of gas in. this manner, steam is 'ledinto the rear of the burner'from pi es 6, air as a uence being -entraine by the l steunt I c rried into the burner through lthe mi; tu

7i. The steam and air pass.

l0 arounr 't- `elp ipltery of the cone. 12 `into the mixmglqh xnber above referred to. At this point the tnyent of mixed steam and air meets the p'positelyfmoving jets of fuel gas, and as u conscquence a thoroughly homogeneous mixture of these fluids is pro' duced. After this has takeny place, the combustible mixture passes tothe front of theA burner around the sides of the hollow-head 8 and the mixturcis once more subjected lto a mixing andjet. forming action by bein led through the hollow member 14. The combustible mixture after passing through the member 14 is carried 'to the front end of the burner casing 1 and is burned.

` Although-I have arranged the parts in my burner in such a way that they are adinstable with relation to one another, vnevery theless the burner can be constructed, if so desired. with all the parts fixed or nonadjustable when once the proper position of the various parts has been ascertained,

` for any gas having an unva ing composif tion. It -will also be seen t at, numerous changes can be made in the construction and location f the various parts without dei parting f .om the spirit of my invention.

j Changes might be made in the manner of operation of the burner, and among such changes it. is to be understood 'r'nu't the pipes' the airand steam. and meansl for injecting.

into said mixing chamber in` an opposite direction to the current.. of air and vsteam n current of fluid fuel.
